SPINDLE.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed May 26, 1905. Serial No. 262.440.

To ztZZ whom itmaq concern/.

Be it known that I, HARRY 0. SMITH, a citizen of the United States,residing at WVillimantic, in the county of Windham and State ofConnecticut, have invented a new and useful Improvement in Spindles, ofwhich the following is a specification.

This invention relates to bobbin-supports, and is particularly valuablefor use in that class of frictionally-driven horizontal bobbinspindlescommonly used in silk rewinding and doubling and twisting machinery.

The object of my present invention is to provide a spindle having aweighted head Whose circumferential wall (that engages thedriving-pulley) is of wood. I thus provide a driving-pulley of metal anda driven spindle whose engaging surface is of such a nature that it willinsure a better frictional contact with the said driving-pulley than amuch heavier spindle constructed entirely of metal.

My invention is illustrated in the accompanying drawings, Figure 1 beinga front side elevation of a spindle of my improved construction and itsdriving-pulley, and Fig. 2 is an end elevation of the same parts. Fig. 3is a side view of a spindle embodying my invention, the head 9 andconnected parts being in central longitudinal section. Fig. 4 is atransverse section of the head g, taken on line 4 4 of said Fig. 3. Fig.5 is a relatively enlarged sectional view of the mid-portion of thespindle f, showing particularly the manner of supporting the spring isby means of which a bobbin is held frictionally on said spindle.

In the drawings the letters a a denote j ournal-bearings, in whichismounted a shaft 1), on which is fixed a pulley c, of metal.

(1 d denote bearings, in which is revolubly mounted a spindle of myimproved construction, said spindle having mounted thereon a bobbin 6.

My improved spindle consists of a spindle proper, f,f0rmed,preferably,of wood and having its end portions extended to engageand revolve in the bearings d d. Secured to the spindle f is an enlargedhead 9, also of wood, which head is counterbored from one end to receivea ring or bushing h of lead or other heavy material. When the describedparts are assembled, they are secured together, and thus becomepractically a single structure, by a pin t, that is driven through saidparts, as seen in Fig. 3 of the drawings. This construction provides ahead of wood for frictional cooperation with the metallic drivingpulleyc, and the metallic bushing inserted therein provides a degree of weightsufiicient to hold the said head in close engagement with said pulley. Ithus provide a reasonably light,, cheap, and serviceable spindle. Thespindle f is grooved longitudinally throughout a part of its length onits opposite sides, and in the grooves thus provided are located springsit of a well-known form for retaining the bobbin e on said spindle.

Having thus described my invention, I claim A spindle proper, anenlarged wooden head secured thereto and having an annular recessbetween its central portion and its outer wall, a bushing of heaviermaterial secured in said recess to add weight to said head, and meanspassed through said spindle, central portion and bushing and through theouter wall of the head.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
